In a few weeks I'll be flying a round trip SMF-SLC-BOS on DL. My only previous experience with Delta was back in Jan. 2004, a fairly short trip on an MD-88 and a Comair CRJ. I was satisfied enough with the service on those flights, but I've never been on a transcon flight with them, so I'm wondering what to expect, and if anything's changed since back then.

The aircraft as listed on my itinerary are 757, 752, 752, 738. I assume 757 and 752 denote the two different configurations for the 757-200. What's the IFE like on these planes, and what sort of snack/BOB service does DL provide on these flights?

I think 752 denotes the ex-Song planes with the Satellite TV. On those flights, you'll have 25 or so channels of TV, games, on-demand movies & customizable music playlists from the database of music in the system.

Your 757 & 738 flights will be traditional IFE. The 757s have video monitors over the aisles, while the 738s have flip-down screens. Not sure if you'll get a movie on those flights, as I'm not sure how long SMF-SLC is. You'll probably get Delta Horizons at least, though, which is a mix of sitcoms, news shows, fine living shows & other stuff. The 738s have the Airshow map, which you can ask the F/As to flip on for at least part of the flight.

Usually the snack is either a bag of peanuts or their Biscoff cookies & a drink. Not sure about BOB. I haven't done a trans-con with DL in years.

Most likely you'll have an ex-song aircraft on the SLC-BOS run so you'll have the PTV's. You'll most likely get a nice snack box with a few little snacks, followed by a later choice of sun chips, cookies, or peanuts. I don't believe there is a BOB option since I've never had one on ATL-PDX. Have a good trip.

One more question -- According to SeatGuru, in order to use my own headphones I'll have to buy a special two-pronged adaptor. When I've flown on CO, who also uses two pronged headsets, my experience has been that my own headphones still sort of work, I just only get sound in one ear. Is this the case on DL as well, or are their headsets different still?
